General Instructions: Moving through the Bell Maps

Bell's Path to the Telephone is a series of "maps" which describe Bell's
invention processes. These maps are of two varieties: active maps, and
inactive maps. Active maps are those which are outlined in blue. From such
maps, you can move to other map pages. Maps which are outlined in black rather
than blue are inactive. These map pages are at the bottom level of the project.
From them, you can only move backward using the Mosaic navigation buttons
at the bottom of the window.

Note that the Master Map is an active map. From it, you can move to a sub-level
by clicking on a "hot box." "Hot boxes" are those rectangles within the maps
which are bold outlined. Notice in the map below (a selected section of the
Master Map) that the box labeled "Gallows Telephone"
is outlined, while the box labeled "Spark Arrester" is not. By clicking on the
outlined box, you can move to a more detailed description of the information
contained in the box. If you click on any portion of the map which is not
active link, you will be returned to the table of contents page.

Some active maps also have "tunnels." These are live links to other maps
in the project. These tunnels are meant to indicate a connection in Bell's thought
processes which cannot be indicated in the general top-down structure of the master map.
Tunnels are pentagonal boxes, such as the one shown below:

In the small sample map below, "To Flame Ganvanometer Experiments" is a tunnel
"from" the current page to the Flame Galvanometer Experiments page. Tunnels can
also lead into pages, such as the one labeled "From Manometric Flame." This
incoming tunnel shows that the map can be entered from the Manometric Flame map,
via outgoing tunnel. Note that active tunnels are not bold-oultined, as are the
other map links.
